Specification of VALQUALON Gasket 7020
VALQUAFLON 7020
In order to improve the cold flow (creep phenomenon),
which is a drawback in PTFE, these gaskets are shaped by
means of a special manufacturing process where
inorganic filler material is compounded. Provided with
heat resistance, chemicals resistance, and anti-cold flow
property, they are best suited for lines handling various
chemicals (high concentrated hot sulfuric acid, hot nitric
acid, etc.). However, they are not suited for high
concentrated alkali such as sodium hydroxide and
hydrofluoric acid.
